Luthier's Featherweight Digital Caliper

About This Item

A shop favorite, now more affordable than ever!
Our Luthier's Featherweight Digital Caliper is the perfect first step to doing better, more precise work.

Great for apprentices and for travel
By machining this caliper out of ultra-durable resin instead of metal, we've made a tool that is perfect for apprentices, students, or your traveling toolkit. It offers the same precision of our original Luthier's Digital Caliper—at about half the weight.

Customized for fretwork!
We added a custom jaw notch for accurately measuring fretwire crown height (the height above the fretboard). This is essential for comparing new wire to original wire. And thanks to a great idea by repairman Frank Ford, we've also added a notch on the depth gauge to measure fret height on the instrument—a real time saver.

Handy for lots of other measuring jobs in the shop—nuts, saddles, tuners, tool setups and more. Featuring LCD digital readouts in inches and millimeters. It measures outside, inside and depth dimensions up to 6" (154mm), with super-accurate 0.0005" (0.01mm) resolution.

  • Made of ultra-durable resin for lighter weight
  • Measures fret height before AND after fret installation
  • Accurate readouts in inches and millimeters
  • Accurate 0.0005" (0.01mm) resolution
  • Measures outside, inside, and depth dimensions
  • CR2032 battery included

These calipers are perfect for light jobs and quick measurements. Need something heavier duty? Our original Luthier's Digital Caliper is made from stainless steel and has extra features for a lifetime of use in a busy shop. The extra versatility and precision have kept them on pro benches for years.

Not happy


Verified Buyer

I tried using them the other day on one of my Guitars and wasn't happy with the results, very clumsy and inaccurate.


Excellent value; Serviceable for equipping staff


Verified Buyer

I ordered about 15 of these to equip a fleet of guitar technicians, and they seem to work very well. They are not the best-of-the-best as far as calipers go, nor are they meant to be; Readings can be skewed with varying pressure so diligence is required for precision, but as far as general measurement goes they work very well. They have all the luthier-specific mods to usual calipers that StewMac has enshrined in their more expensive calipers, which is what makes these really nice for the price. The main thing I do not like about these: they have an auto-on function, which turns the caliper display on whenever it senses a movement of the jaws. It's not as sensitive as some calipers I've seen, but this sensitivity varies across the lot I purchased, and if these did not have that feature then I would rate them a solid 5-stars for their purpose.
